Of course make sure your heater isn't stuck on. Give us a list of every pump in the system.

thanks for the advise man, i will try some fans i have about three i will cut hood and fit them how long will it take to cool the temp down fella is it a period of 12 hours or so because the fans dont seem to blow too much not much air from them i mean is there a more powerfull one i should use ????

To cool a tank, you want to encourage evaporation. Unfortunately this means you'll be putting back into the system a lot of distilled or RO/DI water. You can run fans across any of the open water areas, including the top of the tank (if you remodel the top) and the sump (assuming it may be an open area of water).

Just as important as putting fans in/on the tank, is the room where the tank is located. That room has to have air circulation too -- you want the room to get fresh air and to move air around the room (as well as in and out of the room). Thus the room needs to have ventilation.

You mention starting up. Thought you should see this post, if you haven't come across it yet: Starting up a Marine Aquarium.

try hanging your lights above the tank.. I chose not to put a lid on my tank due to temp problems, this seemed to help a bunch droped temp about four degress

Got it sorted at last

Ok guys a massive thank you from the british side of the equator for all your suggestions and help you have given me, i have tried my original idea of cutting the hod, in the rear where cant be seen i have cut three holes in series 75mm in diameter and have mounted 3 P.C 180mA 12 volt fans, they do resonate a little on the wood but may add a gasket if it annoyes me. The modification seems to have really done the trick its downed the temperature from around 27.6 degree's to 23.7 degree's with no lighting, how good is that i have been experiementing by disconnecting fans so now running 2 fans and have a nice and stable system running at 23.9 at worse case lovely.

so just thought i would update you all thanks again stuart

The problem is unless its already hot where your at you shouldn't need fans with no lights. Either the ambient temps are high or you have a pump heating the tank. If its not ambient temps then you may have issues once it does get hot in the summer.
